43
What is portal hypertension? What is it caused by?
(slides)Portal hypertension – high blood pressure in the portal venous system – main issue that’s going on – portal vein is getting backed up – causes esopageial varieses and have a back up going into the spleen Portal hypertension is abnormally high blood pressure in the portal venous system caused by a resistance to blood flow

49
Patho process for pyloric stenosis
1.) Muscle fibers thicken so the pyloric sphincter becomes enlarged and inflexible 2.) Extra effort to force gastric contents may cause muscle layers of stomach so they become hypertrophied as well Band around the sphincter is to tight and causes vomit
50
What are the stages of colon cancer?
▪ Stage 0: * Carcinoma in situ *cancer cells are only in the inner lining of the colon or rectum (Mucosa) ▪ Stage 1 * Through to muscle layer -tumour has grown into the layer of connective tissue that surrounds the mucosa (submucosa ▪ Stage 2 * Involves serosa -into tissues beyond the muscle layer into other organs ▪ Stage 3 * Lymph nodes involved ▪ cancer cells in lymph nodes near the colon or rectum ▪Stage 4 * Metastasis -cancer has spread to other parts of the body (called distant metastasis), such as to the liver or lungs
51
What are the 3 stages of alcoholic liver disease?
1.) Steatosis – Fat deposition in the liver – lipids from adipose tissue or dietary intake contribute to fat accumulation -Can be caused be low volumes of alcohol *At this stage it is reversible if patient stops drinking 2.) Fibrosis – -Increased hepatic storage of fat -Inflammation and degeneration leads to necrosis of hepatocytes -Stimulates irreversible fibrous characteristics -Harding 3.) Cirrhosis – -Caused by chronic alcoholism and malnutrition -Cell damage initiates an inflammatory response that results in excessive collagen formation -Fibrosis and scarring alter the structure of the liver which obstructs biliary and vascular channels Irreversible
